DESCRIPTION:
System Sensor's intelligent module products are designed to
meet a wide range of applications. Monitor and control
modules can be used to supervise and activate sounders,
strobes, door closers, pull stations, waterflow switches,
conventional smoke detectors, and more. Each module is
rigorously designed and tested for electromagnetic
compatibility and environmental reliability, in many cases
exceeding industry standards. Modules are addressed with
easy-to-use rotary code switches.
Full size modules mount in standard 4” x 4” x 2 1/8 junction
box. Wiring terminals are easily accessible for
troubleshooting purposes.
M500M Monitor Module, M501M Mini Monitor Module,
and M500DM Dual Input Monitor Module
System Sensor's monitor modules provide an interface to
contact devices, such as security contacts, waterflow
switches, or pull stations. They are capable of Styles A and B
supervised wiring to the load device (M500M is capable of
Style D). Conventional 4- wire smoke detectors can be
monitored through their alarm and trouble contacts, wired as
an initiating loop to the module.
In addition to transmitting the supervised state of the
monitored device (normal, open, or short), the full analog
supervision measurement is sent back to the panel. This
allows impedance changes in the supervised loop to the
monitored device to be detected.
The M500DM is capable of monitoring two separate Class B
circuits simultaneously, making it ideal for waterflow tamper
switch and flow switch monitoring.
The small size of the M501M allows it to fit inside devices or
junction boxes behind devices.
M500X Isolator Module
The M500X Isolator Module is an automatic switch that
opens when the line voltage drops below four volts. Isolator
modules should be spaced between groups of sensors or
modules in a loop to protect the rest of the loop. If a short
occurs between any two isolators, then both isolators
immediately switch to an open circuit state and isolate the
devices between them. The remaining units on the loop
continue to fully operate. No more than 25 devices are
recommended for each group.

Monitor Module & Mini Monitor Module
M502M Zone Interface Module
The M502M Zone Interface Module allows intelligent
panels to interface and monitor two-wire conventional
smoke detectors. All two-wire detectors being monitored
must be UL or ULC compatible with the module.
The M502M is addressed through the communication
line of an intelligent system. It transmits the status of one
zone of two-wire detectors to the fire alarm control panel.
Status conditions are reported as normal, open or alarm.
The interface module supervises the zone of detectors
and the connection of the external power supply.
M500S Control Module
The M500S Control Module provides supervised
monitoring of wiring to load devices that require an
external power supply to operate, such as horns,
strobes, or bells. It is capable of Styles Y and Z
supervision. Upon command from the control panel, the
M500S will disconnect the supervision and connect the
external power supply across the load device. The
disconnection of the supervision provides a positive
indication to the panel that the control relay actually
turned on. The external power supply is always relay
isolated from the communication loop, so that a trouble
condition on the power supply will never interfere with
the rest of the system. Full analog measurement of the
supervised wiring is transmitted back to the panel and
can be used to detect impedance changes or other
special test functions.
M500R Relay Module
The M500R Relay Module contains two isolated sets of
Form-C contacts, which operate as a DPDT switch. The
module allows the control panel to switch these contacts
on command. No supervision is provided for the
notification appliance circuit.
